HEAVY DUTY KNIFE GATE VALVE
The ET model knife gate is an uni-directional lug type valve designed according to
MSS-SP-81 and TAPPI TIS 405-8 for industrial service applications.
The design of the body and seat assures non-clogging shut off on suspended solids
in industries such as:
Pulp and Paper
Power plants
Mining
Chemical plants
Wastewater
Food and Beverage
etc.
Sizes: DN 50/2” to DN 900/36” (larger diameters on request)

DESIGN FEATURES
BODY:
One piece integrally cast stainless steel body with reinforced ribs in larger
diameters for extra body strength.
Internal cast gate wedges and guides allows for tighter shutoff.
Port design according to MSS-SP-81 and Tappi TIS 405-8.
Internal design avoids any build up of solids that would prevent valve from
closing.
GATE:
Standard AISI 316 stainless steel gate.
Gates polished and lapped for a greater seal between the gate with both
packing and seat.
Bottom of the gate edge is machined to a bevel to cut through solids for a
tighter seal in the closed position.
SEAT: (resilient)
Unique design that mechanically locks the seat in the internal of the valve
body with a stainless steel retainer ring.
Standard EPDM; also available in different materials such as Viton, PTFE,
etc.
PACKING:
Standard braided PTFE impregnated fibre with EPDM o-ring for better shut
off, with an easy access packing gland ensuring a tight seal
Long-life braided packing is available in a wide range of materials.
STEM:
The standard stainless steel stem offers a long corrosion resistant life.
For rising stem handwheel actuators only, a stem protector is provided for
additional protection against dust while the valve is in the open position.
ACTUATORS:
All actuators supplied by ORBINOX are interchangeable, and supplied
with an standard mounting kit to allow for installation on site.
YOKE or ACTUATOR SUPPORT:
Made of EPOXY coated steel (stainless steel available on request).
Compact design makes it extremely robust even under the most severe conditions.
EPOXY COATING:
The epoxy coating on all ORBINOX cast iron and carbon steel valve bodies
and components is electrostatically applied making the valves to be corrosion
resistant with a high quality finished surface.
The ORBINOX standard colour is RAL-5015 blue.
GATE SAFETY PROTECTION:
ORBINOX automated valves are provided with gate guards in accordance
with EU Safety Standards.
The design feature prevents any objects from being caught accidentally
while the gate is moving.

OTHER OPTIONS
Bonnet (Fig.1):
Assures tight sealing to atmosphere for use with hazardous gas or
fluids.
Reduces packing maintenance.
V-port:
60 degree and pentagonal port design.
Selection depends on type of fluid control desired.
Flush ports:
Allow for cleaning of solids trapped within the body cavities that can
obstruct the flow or prevent the valve from closing.
Purging can be made with air, steam, liquids, etc. depending on the
process.
Other materials of construction:
Special alloys such as AISI 317, 254SMO, Hastelloys, Titanium,...
Fabricated valves:
Orbinox is equipped for in house fabrication of special valves.
Depending on the design, diameter, pressures, material of construction,
etc.

SURFACE TREATMENTS
Valve components can be protected or coated for a longer life expectancy,
depending on the application and the service
conditions.
At ORBINOX we can offer treatments and coatings for the valve components to improve the properties against abrasion (Stellite, Polyurethane…),
corrosion (Halar, Rilsan, Galvanised…) and adherence (Polishing,
PTFE…).
ATEX
Please contact our Orbinox representative for info and availability.
Some considerations:
Hand operated ET valves have been subjected to an ignition risk
assessment according to DIN EN 13463: 1-5 and they are out
the scope of application of ATEX Directive. Therefore hand operated valves are suitable for ALL ATEX zones.
Electrical, pneumatical and hydraulically operated valves must be
subjected to a conformity assesment of their own and also of the
whole unit valve-actuator to get EC Type Approval to Directive
94/9.
We recommend consultation with our technical department.
